ioxclaims. (cidad-111) `lhis invention relates to valvesand has Vfor its object to: provide a new and'fimproved-vdevice of this description. iThe invention has as a further obj ectV to provide a combination shut! off yand throttle valve. "The inventionl has la furth'erfob- Yject toV provide` a valve-which can be used'bothon 1 high Ipressure -and f low pressure systems. The

invention has vas afiurther objectV to providea 'silent throttling-valve. 'fTheinvention has further objects vv`vhich-are more particularly pointed out lin the accompanyingY description.

Referringnow toA the drawing;-f Fig. -l is a View ofone fornrof valve 'embodying the invention;

Fig- -2= is aV vertical-sectional? View therethrough f Fig. 3 is anenlarged--sectionaljview through' the throttling valve.

Like-i. umerals ref er to flike parts throughout the several figures.

In the construction shown'the valveis'provided Y With'a casing 1I havingan inlet 2 and an outlet 3.

Theinlet? is provided with avalve Iseat 4.` A vmainvalver member 5 is movably mounted in position so that itfmay be downon the valve-seat 4 to closethe inlet. Thisvalve'may bejmounted in any Jdesired manner.

Asherein shown it-isV mounted-in aplugi screw Athreaded into the casing I. *The-valve 5 is provided -with'a lstem -vvhich consists of two parts, a

part 'I whichpasses*through an opening in the *plug 6 and'athreadedfpart lwhic'h is connected with 'thevalvefmember 5 in anyf'desired manner,

` as Yby Amea-ns'cf the Areduced portion-9 -and 'the vnut -|0. The-threaded part B works infathreaded opening Il in the part 1 of^thestem. Thegpart 1 of the stem is-rotatable and isprovidedwitha hand piece ,I 2Y for this purpose, which khas its-edge Y i3; bent downwardly over the upper -end'of the plug 6. vIhe'part l of the stem has a collar or annulus I4`wluchworks in a groove-.15 in the 'plug' '6 sothat while the part 1 `may be Vrotated it will n ot move longitudinally.

uForpurposes of assembly `the groove1`5 is enlarged at its flower end I6 and ascrew threaded ringfl'l surrounds the part 1 of thestemandV engages the lower face 'ofthe annulus II 4; as Nclearly shown in Fig. 2. The 'valve member 5 andthe part 8 ofthe valve `stem'is prevented ,from'rotat A lng when the'stem portion 1 is rotated so, that its motion is connedjto a longitudinal inA vand out motion. This is securediby providing 1a, pin `I8 which is connectedwith the valve' member and which slides in arecess I9 in thevplug 6. It will -be/seen thatfwhen the stem section 1 is rotated the threaded section 8 of the stem will be moved toward or fromthe seat 4,1butwill'ntrbe rotated.V

The valve member 5, therefore, may-,bejmoved against the valve seat 4 to entirely shuttoi'gthe iiovv'vv of the water between- 'said valvef 2 seat` and -t'heV-valve member.` .fConnecte'dwith the 'ifnlet'f2 below the valveseat'isa bypass 2l) whichfflaEds-.f

-t'o an opening. 2 l communicating withr the' "interior Cof the valvefeasingf-alnd withthe outlet`3. Slidf vably nfiol-lnted-` in this openingfZI-is af throttle member 22 -vvhich is connected "with a threaded stemrZS working in athreaded opening infaplugl 24. The end ofs the threaded member 'is'K-provided with a tool-notch 25 andlis'normally lcove'redfup screen devieehaving'small openings lwhichper- .15

'mit water tovpass therethrough.

` This screen device maybe made'in'anytlesired I:manner andi asi herein" Shown consists l of a Iriain member 28, see "Fig 3, which Ihasea1'c5'1lindrica1 vform witha periphery 29 vand the bentfedges-'30 y2@ :LandlSl whichfare'clamped betweenv the members :S2-and 33 by means of a -nutf34`onthe 'reduced end-oi the steml'23. Thisfscre'enrmemberlis'preferably madeup of adouble 'layer ofvffine "screen and there is also'prferably on the int'erior'threoi 25 alplurality of screenmembers'f35. fi It willibe seen "that by vmoving the throttlingmemberinwardlyin the openingl, the portionv of the screentl'irough which the Water can pass is decreasedso as'fto i reduce the amount of waterlpassing therethrough. 1; 30 When Vthe throttli'ng-device is moved/outwardly the waterpasse'sfthrough a greater vportionof V*the screen, V and l'ien'eel more Water Ican i pass therethrough.

L Whenlthe valveis used on a low pressure system s 35 the valve member 5 is openedf'and the water Lpasses throughV the inlet and between the valve seat Yll'and then thevalve member 5 ajridoutthe outlet'. When the valve-is used onfa high pressure system the valve member 5 is entirel'yclosed `byge() f being moved opposite 'the valve l yseat 4,` but not Venough to closevo'f-the bypass 20 andthe w'ater passes through the 'bypass"Zvfandthroughthe ltlrro'ttlingrriiember 22,y passing through the screen and'through the opening 2`I-.and theneout`flthe45 outlet 3. It will be seen thatfbyrme'ans ofth'is ide'vi'ce the Water can be properly controlledfor the high pressure so that the proper lamount' will pass through the valve. By moving th'elv lve 5 down upon `'the top of the valve seatf4athefby- 50 pass 2|] is closed. I have therefore here Ia combination shutloi and throttle valvewhich eliminates objectionable linel noise atfa'ny pressures.

has a throttled water way, the water being diverted through the bypass and through the throttling device which prevents all noise and splashing. This throttle member is easily removable for cleaning by simply unscrewing the plug 24, the throttle member coming out with the plug. It can then be easily cleaned or repaired or replaced. In order to clean the valve 28 the valve 5 is moved down on to the seat 4a so as to entirely shut off the water passing through the casing. This construction makes it unnecessary to shut off the water in the main when it is desired to clean this valve. The main valve 5 may also be used to regulate the water passing through the bypass 2li, by moving it partially across the mouth of said bypass. It will further be noted that there are two inlets to the casing, one controlled by the valve 5 and the other controlled by the valve 28, and that the water which passes through the valve 28 passes by the valve 5'on its way to the outlet 3.
